End-of-life care trajectories among older adults with lung cancer

IntroductionMedicare decedents with cancer often receive intensive care during the last month of life; however, little information exists on longer end-of-life care trajectories.Materials and MethodsUsing SEER-Medicare data, we selected older adults diagnosed with lung cancer between 2008 and 2013 who survived at least six months and died between 2008 and 2014. Each month we assessed claims to assign care categories ordered by intensity as follows: full-month inpatient/skilled nursing facility > cancer-directed therapy (CDT) only > concurrent CDT and symptom management and supportive care services (SMSCS) > SMSCS only > full-month hospice. We assigned each decedent to one of six trajectories: stable hospice, stable SMSCS, stable CDT with or without concurrent SMSCS, decreasing intensity, increasing intensity, and mixed. Multinomial logistic regression estimated associations between socio-demographics, calendar year, and area hospice use rates with end-of-life trajectory.ResultsThe sample (N = 24,342) was predominantly aged ≥75 years (59.4%) and non-Hispanic White (80.5%); 19.1% lived in healthcare referral regions where ≤50% of cancer decedents received hospice care. Overall, 6.5% were continuously hospice enrolled, 25.6% received SMSCS only, and 29.4% experienced decreasing intensity; 3.9% received CDT or concurrent care, while 8.7% experienced an increase in intensity. Higher healthcare referral region hospice rates were associated with decreasing end-of-life intensity; Black, non-Hispanic decedents had a higher risk of increasing intensity and mixed patterns.DiscussionAmong older decedents with lung cancer, 62% had six-month end-of-life trajectories indicating low or decreasing intensity, but few received persistent CDT. Demographic characteristics, including race/ethnicity, and contextual measures, including area hospice use patterns, were associated with end-of-life trajectory.     

Associations between frailty and cancer-specific mortality among older women with breast cancer

Purpose

To analyze whether monitoring serum estradiol (E2) levels using a highly sensitive and specific liquid chromatography tandem mass spectrometry (LC–MS/MS) method may identify patients with AI failure with E2 levels below the lower limit of quantification (LLOQ) after schwitching from tamoxifen to letrozole.

Methods

In a prospective study of breast cancer patients switching to letrozole treatment after previous tamoxifen, plasma estrogen levels were measured at baseline and after 3- and 12-months using LC–MS/MS.

Results

Forty-six patients were classified postmenopausal and entered into the final analysis. Thirty-nine (85%) patients had three- and 12-month E2 concentrations below the LLOQ (5 pmol/L). In the seven patients classified as AI-failures during letrozole treatment, serum E2-MS level rose above 5 pmol/L at 3 months with a mean E2-MS 77.5 pmol/L or 12 months with a mean E2-MS 21 pmol/L. None of the baseline variables i.e., age at diagnosis, age at study entry, age at menarche, BMI, endometrial thickness, total ovarian volume, baseline FSH, E2-IA, or E2-MS were significantly associated with the risk of AI failure in logistic regression. E2 levels at baseline measured by E2-IA did not significantly correlate to the levels measured by E2-MS.

Conclusions

There is a relatively high risk of inadequate estrogen suppression in patients who switch from tamoxifen treatment to AIs. The use of sensitive and specific assays, such as LC–MS/MS methods, to monitor estrogen levels during AI treatment is essential to minimize the risk of a proceeding inefficient endocrine therapy.

     

Associations between illness burden and care experiences among Medicare beneficiaries before or after a cancer diagnosis

IntroductionTo understand associations between a new measure of illness burden and care experiences in a large, national sample of Medicare beneficiaries surveyed before or after a cancer diagnosis.Materials and MethodsThe SEER-CAHPS Illness Burden Index (SCIBI) was previously developed using Surveillance, Epidemiology, and End Results (SEER)–Consumer Assessment of Healthcare Providers and Systems (CAHPS) linked data. The SCIBI provides a standardized morbidity score based on self- and other-reported information from 8 domains and proxies relative risk of 12-month, all-cause mortality among people surveyed before or after a cancer diagnosis. We analyzed a population of Medicare beneficiaries (n = 116,735; 49% fee-for-service and 51% Medicare Advantage [MA]; 73% post-cancer diagnosis) surveyed 2007–2013 to understand how their SCIBI scores were associated with 12 different care experience measures. Frequentist and Bayesian multivariable regression models adjusted for standard case-mix adjustors, enrollment type, timing of cancer diagnoses relative to survey, and survey year.Results and DiscussionSCIBl scores were associated (P < .001) in frequentist models with better ratings of Health Plan (coefficient ± standard error: 0.33 ± 0.08) and better Getting Care Quickly scores (0.51 ± 0.09). In Bayesian models, individuals with higher illness burden had similar results on the same two measures and also reported reliably worse Overall Care experiences (coefficient ± posterior SD: −0.17 ± 0.06). Illness burden may influence how people experience care or report those experiences. Individuals with greater illness burdens may need intensive care coordination and multilevel interventions before and after a cancer diagnosis.     

Associations among survivorship care plans,experiences of survivorship care,and functioning in older breast cancer survivors: CALGB/Alliance 369901

Purpose

Survivorship care plans (SCP) are recommended for all cancer patients and could be especially useful to survivors 65 years and over (“older”). This study examined receipt of SCPs among older breast cancer survivors and whether SCPs were associated with improved patient-reported outcomes.

Methods

Three hundred and twenty-eight older women diagnosed with invasive, nonmetastatic breast cancer between 2007–2011 were recruited from 78 cooperative-group sites. Participants completed telephone interviews at baseline and 1-year posttreatment. Regression analyses examined SCP receipt (yes/no) and functioning (EORTC-QLQ-C30), cancer worry, and experiences of survivorship care (care coordination, knowledge).

Results

Only 35 % of women received SCPs. For each 1-year increase in age, there was a 5 % lower odds of receiving an SCP (odds ratio (OR)?=?0.94, 95 % confidence interval (CI) 0.91–0.98, p?=?0.007). Besides age, no other factor predicted SCPs. SCP receipt was associated with greater knowledge and understanding of requisite follow-up care (p?Conclusions Receipt of care plans was limited. SCPs improved understanding of breast cancer follow-up care among older survivors, but did not impact functioning one year post-treatment.

Implications for Cancer Survivors

To impact functioning and salient needs of the growing cohort of older survivors, survivorship care plans likely should be tailored to geriatric-specific issues. To improve functioning, SCP content should expand to include exercise, nutrition, polypharmacy, social support and management of symptom burden from cancer, and other comorbid conditions. To improve follow-up care for cancer survivors, SCPs should delineate shared care roles between oncology and primary care in managing recurrence surveillance, screening, and cancer sequelae.     

Knowledge,beliefs, and misconceptions about palliative care among older adults with cancer

IntroductionOlder adults with cancer have high symptom burden and unmet needs and may benefit from palliative care (PC). However, little is known about their knowledge and understanding of PC. This study examined the knowledge, beliefs, and misconceptions about PC in older adults with cancer in the United States.Materials and MethodsWe used data from National Cancer Institute's 2018 wave of the Health Information National Trends Survey (HINTS). A total of 370 individuals aged 65 and older with a diagnosis of cancer were included in this study. The outcomes included PC knowledge, goals, and misconceptions. The main predictors included general health status, chronic conditions, functional limitations, and types of cancer.ResultsAbout two thirds of the sample (65.31%) did not have any knowledge of PC. Among those who had some knowledge, they had good understanding of PC goals, but also had many misconceptions about PC. Multiple regression analysis showed that older age (p < .001), racial minority (p = .021), and lower education (p = .001) was associated with lacking knowledge of PC. Individuals with some functional limitations tended to have better understanding and fewer misconceptions of PC.DiscussionThe knowledge about PC is low in older adults with cancer in the US. Educational interventions need to be implemented to increase knowledge and reduce the misconceptions about PC in this population. Increasing knowledge of PC may ultimately lead to increased access to PC and improve the quality of life in this population.     

Associations between autoimmune conditions and hepatobiliary cancer risk among elderly US adults

Growing evidence suggests that people with autoimmune conditions may be at increased risk of hepatobiliary tumors. In the present study, we evaluated associations between autoimmune conditions and hepatobiliary cancers among adults aged ≥66 in the United States. We used Surveillance, Epidemiology, and End Results (SEER)-Medicare data (1992–2013) to conduct a population-based, case–control study. Cases (n = 32,443) had primary hepatobiliary cancer. Controls (n = 200,000) were randomly selected, cancer-free adults frequency-matched to cases by sex, age and year of selection. Using multivariable logistic regression, we calculated odds ratios (ORs) and 95% confidence intervals (CIs) for associations with 39 autoimmune conditions identified via Medicare claims. We also conducted separate analyses for diagnoses obtained via inpatient versus outpatient claims. Sixteen conditions were associated with at least one hepatobiliary cancer. The strongest risk estimates were for primary biliary cholangitis with hepatocellular carcinoma (OR: 31.33 [95% CI: 23.63–41.56]) and primary sclerosing cholangitis with intrahepatic cholangiocarcinoma (7.53 [5.73–10.57]), extrahepatic cholangiocarcinoma (5.59 [4.03–7.75]), gallbladder cancer (2.06 [1.27–3.33]) and ampulla of Vater cancer (6.29 [4.29–9.22]). Associations with hepatobiliary-related conditions as a group were observed across nearly all cancer sites (ORs ranging from 4.53 [95% CI: 3.30–6.21] for extrahepatic cholangiocarcinoma to 7.18 [5.94–8.67] for hepatocellular carcinoma). Restricting to autoimmune conditions diagnosed via inpatient claims, 6 conditions remained associated with at least one hepatobiliary cancer, and several risk estimates increased. In the outpatient restricted analysis, 12 conditions remained associated. Multiple autoimmune conditions are associated with hepatobiliary cancer risk in the US Medicare population, supporting a shared immuno-inflammatory etiology to these cancers.     

Use of complementary medications among older adults with cancer

BACKGROUND:

Little is known about complementary medication use among older adults with cancer, particularly those who are receiving chemotherapy. The objective of this study was to evaluate the prevalence of complementary medication use and to identify the factors associated with its use among older adults with cancer.

METHODS:

The prevalence of complementary medication use (defined as herbal agents, minerals, or other dietary supplements, excluding vitamins) was evaluated in a cohort of adults aged ≥65 years who were about to start chemotherapy for their cancer. The associations between complementary medication use and patient characteristics (sociodemographics; comorbidities; and functional, nutritional, psychological, and cognitive status), medication use (number of medications and concurrent vitamin use), and cancer characteristics (type and stage) were analyzed.

RESULTS:

The cohort included 545 patients (mean age, 73 years; range, 65‐91 years; 52% women) with cancer (61% stage IV). Seventeen percent of these patients (N = 93) reported using ≥1 complementary medication; the mean number of complementary medications among users was 2 (range, 1‐10 medications). Complementary medication use was associated with 1) earlier cancer stage (29% had stage I‐II disease vs 17% with stage III‐IV disease; odds ratio [OR], 2.05; 95% confidence interval [CI], 1.21‐3.49) and 2) less impairment with instrumental activities of daily living (OR, 1.39; 95% CI, 1.12‐1.73).

CONCLUSIONS:

Complementary medication use was reported by 17% of older adults with cancer and was more common among those who had less advanced disease (i.e., those receiving adjuvant, potentially curative treatment) and higher functional status. Further studies are needed to determine the association between complementary medication use and cancer outcomes among older adults. Cancer 2012. © 2012 American Cancer Society.     

Predictors of hospital readmission among older adults with cancer

ObjectiveOlder adults with cancer are at higher risk for costly and potentially dangerous hospital readmissions. Identifying risk factors for readmission in this population is important for future prevention of readmission.Materials and methodsHospital discharges among patients ≥ 65 years with solid tumors on non-surgical services from 2006-2011 were reviewed in this matched case-control study. We abstracted patient/cancer characteristics; functional status; fall risk; chemotherapy line; comorbidities; laboratory values; discharge parameters; and miscellaneous information (Do Not Resuscitate Order, pain scores) from medical records. Conditional logistic regression was used for univariate and multivariable analysis.ResultsThis analysis included 184 case-patients readmitted within 30 days after discharge from the index admission and 184 sex- and age-matched control-patients discharged from index admission within three months of the cases with no readmission. Cases and controls had no differences in terms of primary cancer type, treatment, and index admission reason. Cases were more likely to have abnormal hemoglobin, albumin, sodium, and SGOT on discharge. Compared to those with ≤1 abnormal laboratory test, patients with 2 or more abnormal test results were 3 times more likely to be readmitted within 30 days.ConclusionThis study demonstrated that older adults with cancer who had at least 2 abnormal laboratory results (hemoglobin, albumin, sodium, and SGOT) at discharge were 3 times more likely to be readmitted within 30 days compared to those with ≤1 abnormal results. These laboratory values may be predictive of the risk of readmission, and should be monitored before discharge to potentially prevent readmission.     

Association between chemotherapy toxicity risk scores and physical symptoms among older Brazilian adults with cancer

ObjectiveUtilizing the Cancer and Aging Research Group (CARG) chemotherapy toxicity risk score before starting treatment in older adults with cancer is guideline-recommended. However, this has not been tested in most developing countries. We investigated the use of a Portuguese version of the CARG score, including the association between this score and physical symptoms, among older Brazilian adults with cancer.Patients and methodsWe enrolled patients aged ≥65 starting chemotherapy at a public Brazilian hospital. A Portuguese version of the CARG tool was created and linguistically validated. Patients were assessed for chemotherapy toxicity risk using the CARG score, and physical symptoms were evaluated using the Functional Assessment of Cancer Treatment-General (FACT-G) scale. Multivariable logistic regression was used to identify physical symptoms associated with high CARG scores, including pain, nausea, and fatigue.ResultsOlder patients (65+) with cancer were enrolled (n = 117). Patients were mostly female (57.3%), white (52.1%), married (52.1%), and had less than high school education (75.2%). Breast, gastrointestinal and lung cancers were the most common diagnosis, and 66.7% had metastatic disease. Elevated pain scores (P < .01) were associated with higher chemotherapy toxicity risk scores, even after adjusting for potential confounders.ConclusionWe created and implemented a Portuguese language version of the CARG tool. We found that, although physical symptoms are not included in the CARG model, elevated pain was strongly associated with having a high CARG score. As a modifiable risk factor, pain should be addressed among older patients with cancer considering chemotherapy, to help mitigate their risks for toxicity.     

Utilization of palliative care and acute care services in older adults with advanced cancer

ObjectivesThere is a gap in knowledge regarding the rates of utilization of palliative care services (PCS) and acute care services (ACS) among older patients with advanced cancer close to end of life. We analyzed the utilization of these services among older adults (65 years and older) and compared them to those in younger adults (40–64 years) with advanced cancer.Materials and MethodsA retrospective chart review of 567 veterans who died with advanced cancer between 2002 and 2009 and utilized PCS and ACS prior to death was conducted after IRB approval. To assess PCS utilization, we studied the mean duration between day of hospice referral and time of death (DOR) and the mean length of stay with hospice (LoS). The frequency of emergency room visits (ERVLM), hospital admissions (HALM), and ICU admissions (ICULM) in the last month of life was used as a measure for ACS. The differences among older and younger patients were compared using two sample t-tests.ResultsOlder adults had earlier referral to PCS [mean DOR: 47.3 versus 34.5 days, p = 0.015], longer stay with hospice [mean LoS: 32.5 versus 20.2 days, p = 0.007], fewer hospital [HALM: 0.7 versus 0.9, p = 0.043], and ICU admissions [ICULM: 0.1 versus 0.2, p = 0.030] per patient. The proportion of patients utilizing ER visits [53.5 % versus 59.5%, p = 0.173] and hospital admissions [58.6% versus 65.1%, p = 0.13] in the last month of life was similar in both age groups with fewer older adults utilizing ICU care [13.2% versus 19.5%, p = 0.047].ConclusionOlder patients with cancer are likely to be referred to PCS earlier than younger patients and spend a longer duration with PCS prior to death. However, there continues to be significant utilization of ACS in all patients with advanced cancer. Better understanding of the goals of care in older adults with cancer and education of oncology providers regarding the need to utilize and integrate palliative care services earlier in the course of disease is imperative.     

Health care experiences among women diagnosed with gestational breast cancer

Gestational breast cancer (GBC) presents many challenges for women and the clinicians who care for them. The aim of this study was to explore the health care experiences of women diagnosed with GBC to inform and improve clinical care of women in this predicament. Semi‐structured interviews were conducted with 17 women who had been diagnosed with GBC in the previous 5 years. The overarching themes for perceived quality of care were “communication” and “comprehensive care.” “Communication” had two sub themes: “interdisciplinary communication” (the way health professionals from different disciplines communicated with each other about the management of the woman's care) and “patient communication” (how they communicated this to the woman). The “comprehensive care” theme incorporated three sub themes: “the spirit” (psychological care); “the mind” (information provision); and “the body” (management of treatment side effects). Women's own accounts of positive and negative experiences of GBC care provide unique and specific insights which improve understanding of their concerns and needs. The findings can inform advances in quality and efficacy of clinical care; offer guidance for obstetricians, oncologists and allied health professionals about the needs of women diagnosed with GBC and how care can be optimised; and inform the development of resources to assist women and their families.
